attached to the container and body portion vide a container of above theupper score lines, which collar is adapted to enter the body forreclosure after the rip strip is removed.

A further object of the invention is to prothe above type with anintegral band disposed below the upper score line and formed by afolding of the wall of the body ortion.

A still fiirther object of the invention is to provide a container ofthe above type wherein said body portion has an inwardly extending beadserving as a stop shoulder on which the collar rests during reclosure.

In the drawings 1 is a side view of a container embody- Flim t e1mprovements.

ig. 2 is a vertical sectional view through the container with the endapplied and before it is joined to the body b a double seam.

Fig. 3 is a view similar to ig. 2, but showing the body and end joinedby a double seam, and the upper edge of the collar permanently securedto the end and bodyportion.

Fig. 4 is a view showing the rip strip torn away and the cover removed.

Fig. 5 is a view similar to Fig. 3, but showing a slightly modifiedarrangement of the folds in the body wall formingthe band.

The. invention is directed to a container having a body portion to whichthe ends are joined by double seaming. The wall of the body ispreferably folded before the side edges of the blank are joined to formthe body so as to provide an integral band adjacent one end of the body.This band may be formed by the folding of the body wall inwardly oroutwardly. The body wall is scored along lines parallel with each otherand above the lower edge of the band. The score lines are located asuflicient distance from the upper end of the body so that the upperscore line is just below the double seam. The body is also provided withan inwardly projecting bead adjacent the lower end of the integral band.Located within the body of the container is a collar which extends fromthe flange at the upper end of the container body to the shoulder formedby the inwardly projecting bead. The lower edge of this collar ispreferably rolled into a curl. The upper edge of the collar is curvedoutwardly. slightl and nests against the body wall at the ange therein.The cover is provided with the usual depressed central portion and witha flange which is rolled with the flange of the body into a double seam.

Referring more in detail to the drawings, the container embodying theinvention consists of a body portion 1, the side edges of which arejoined by a side seam 2. An end 3 is secured to the body portion bydouble seaming. Before the edges of the blank formin the body are joinedto form the side seam, the blank is folded inwardly at 4 and thenceoutwardly at 5, thus producing an integral band 6. After the side edgeshave been joined, the body portion is provided with an inwardlyprojectingbead 7 The body wall is provided with score lines 8 and 9. Thescore line 8 is just above the upper edge of the band 6 and the scoreline 9 is slightl below the double seam 10, which joins t e end 3 to thebody portion of the container. A collar 11 is provided which fits withinthe body portion. This collar has a curled lower edge 12 and anoutwardly turned upper edge portion 13 which nests against the innersurface of the body of. the container at the flange 14. The end 3 has anoutwardly extending flange 15 which, as noted above, is rolled with theflange 14 into the double seam 10. a When the double seam is formed, theupper edge portion 13 of the collar will be gripped between the verticalwall 16 of the central depressed portion of the end 3 and the upper edgeportion of the body of the container. Thus it is that the collar ispermanently attached to the end and that part of the container bodyabove the upper score line 9.

The body is provided with an integral tongue 17 in line with the ripstrip so that a key may be applied thereto and the metal torn along thescore lines. When the rip strip is removed then the container end isreleased from the main portion of the body of the container. Thatportion of the body wall above the upper score line 9 remains secured tothe end by the double seam.

In Fig. of the drawings, the rip strip is shown as torn away and the endraised, lifting the collar from within the container body. The collarwill be inserted in the container body for reclosure purposes and thecurled edge 12 of the collar will engage the shoulder formed by theinwardly projecting bead 7. This will limit the extent to which thecollar may be moved into the container body. There is sufficient extentof movement between the collar and the container body so as to firmlyhold it in place for reclosure purposes.

In Fig. 5 of the drawings the wall of the container body is shown asfolded at 18 in the forming of the band so as to lie on the outer faceof the container body. Otherwise, the structure is the same as in Figs.1 to 4, except for the fact that the score line 8 is placed lower downwhile the score line 9? is just beneath the double seam 10. The score 7line 8 when placed below the upper edge of the band as shown in Fig. 5produces a container which when opened by removing the rip strip has asmooth upper edge. Furthermore, the raw edge of metal is below thissmooth upper edge and there is little or no chance of the hand being cutby the raw edge of metal.

It is understood that the container end is provided with the usualcoating so that when the double seam is formed, an hermetic seal isproduced. The band produced by the folding of the body wall greatlystrengthens the upper end of the container when opened by the removal ofthe rip strip. The band not only assists in the tearing out of the ripstrip, but it also holds the opened container in proper shape forreclosure. The depending collar which is permanently attached to thecontainer end and the part of the body portion above the upper scoreline becomes a rigid depending portion which forms with the end aneflicient cover for reclosure purposes.

It will be understood that the details of construction of the containermay be greatly varied without departing from the spirit of the inventionas set forth in the appended claims.

Having fully described our invention, what we claim as new and desire tosecure by Letters Patent, is

1. A container comprising a body portion having score lines adjacent oneend thereof forming a rip stri a container end double seamed to said b0y portion and a collar lo cated within the body and permanently attachedto the container end and body above the upper score line and adapted toenter the body for reclosure after the rip strip is removed.

2. A container comprising a body portion the wall of which is foldedadjacent one end to form a band, said body having score lines betweenthe lower edge of the band and the end of the body forming a rip strip,a container end double seamed to said body, and a collar located withinthe body and permanently attached to the container end and body abovethe upper score line, said collar being adapted to enter the body forreclosure after the rip strip has been removed.

3. A container comprising a body portion having score lines adjacent oneend thereof forming a rip strip, a container end double seamed to saidbody portion and a collar located within the body and permanentlyattached to the container end and body above the upper score line andadapted to enter the body for reclosure after the rip strip has beenremoved, said body portion having an inwardly projecting bead positionedso as to serve as a stop shoulder for limiting the extent to which thecollar may be inserted in the container body for reclosure.

'4. A container comprising a body portion the wall of which is foldedadjacent one end to form a band, said body having score lines betweenthe lower edge of the band and the end of the body forming a rip strip,a container end double seamed to said body, and a collar located withinthe body and permanently attached to the container end and body abovethe upper score line, said collar being adapted to enter the body forreclosure after the rip strip has been removed, said container bodyhaving an inwardly projecting bead at the lower edge of the band whichforms a stop shoulder for limiting the extent to which the collar may beinserted in the container body for reclosure.

In testimony whereof, we aflix our signatures.
